Interesting, thank you. After my first child (c-section) I had to inject myself with blood thinners for days afterwards at home. Two years later after another c-section there were no injections of blood thinners. I asked why and they just said, "oh, we don't do that anymore".

At the time I thought "that's weird" but I didn't think too hard about it. I kind of had other things to deal with more urgently! But looking back it was very strange that nobody really adequately explained to me either why I had to have the injections, nor why I suddenly didn't need them 2 years later.
